Stefan LotterBloemfontein - Boom Prinsloo is facing up to one of the toughest decisions of his life.The Blitzbok star is wondering whether he should make a return to the 15-man code in the hope that he will play Super Rugby one day - or whether he should rather continue to play sevens rugby."I think I have another season or so of sevens. But I have a lot to think about," admitted Prinsloo.This week he handed over one of his Bok sevens jerseys to the University of Free State's Rugby Club, where his career really got direction. He made a name for himself in the Shimlas jersey in 2010 when he was named the Varsity Cup's Player of the Year.He made his debut for the Sevens Boks last year.Following a few outstanding performances for the Blitzbokke and with a player like Ashley Johnson in line for World Cup duty with the Springboks, the door is now open for Prinsloo to play his way into Free State's Currie Cup starting line-up.However, the loose forward is enjoying his sevens rugby and has a high regard for Paul Treu as Bok sevens coach - factors that are making his decision all the more difficult.Prinsloo performed well for the Sevens Boks this year as they won the International Rugby Board's tournaments in London and Edinburgh."We won against Fiji in London, but had to pick ourselves up again immediately for the tournament in Edinburgh. The fact that we are always working hard in Stellenbosch, where our base is, helps a lot with our fitness during games. It is particularly the case with tournaments in quick succession," he said."It's an incredible privilege. We (Sevens Boks) are feeling like a small family by now and that is certainly why we're successful."Prinsloo is particularly happy with the 20-19 win over Fiji as he believes the islanders are the toughest team to beat in the code."Fiji are definitely tough. You never know what they are going to bring on the field. Their arms are about as long as your legs and it's their number one national sport."Prinsloo is longing for the exciting 15-man student rugby of the Varsity Cup. However, he does not believe it comes close to the challenge of sevens rugby."It's a completely different game. The Varsity Cup is still student rugby. With sevens rugby you get to compete with international players and are playing at a completely different level."
